Procedure

Two grams (0.0056 mole) of 5-chloro-7,8-dihydro-8-ethyl-7-oxo-2-phenylpyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester (prepared by the method of Example 3, first paragraph) and 0.82 g. (0.011 mole) of diethylamine were added together in ethanol in an autoclave and heated on a steam bath for 2 hours. The reaction mixture was then filtered and the filtrate chilled in ice. The precipitate which formed was collected on a suction filter. Recrystallization from ethyl acetate gave 0.8 g. of product m.p. 110°-115° C.
